CONVERTILE SOFA. CHAIR AND COUCH.

Specification of Letters Patent.

Application led June O 1910. Serial No. 567,762.

To all whom it may concern: y

Bc it known that we7 Jaco Kuoni-inni and' Zot/ran B. Csinr, subjects ot'Austria- Hungary, residing at Cleveland, in the countyot Cuyahoga andState of Chio, have invented certainnew and useful Improvements inConvertible Sofa Chairs and Couches, of which the following is aspecification.

Our invention relates to a convertible sofa chair and couch. the samebeing adapted to be used as a chair with or without a reclin ing backand as a base rocker and also to be opened into a couch or bed, all ashereinlaiter fully described and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a vertical sectional elevation'lront to reary of our invention with the parts in the po sition of'achair but locked in respect to the base to prevent rocking. Fig. 2 is across section on a line corresponding substantially to @@ag Fig. 4,'looking to the right. Fig. 3 is a plan view of a portionA of theinvention showing the parts open to tor-m a bed. Fig. 4 is alongitudinal sectional elevation of the structure partly broken out atone end'and showing the position of the parts as they form a bed.

The invention herein is an improvement more particularly upon theconstruction of a combined chair and'bed 'shown and described in anapplication tiled December 3l, 1909, Ser. No. 535,806. In the furtherdevelopment of said chair and bed a number ot changes have been found tobe necessary to render the structure altogether convenient and desirableand at least some of these are embodied in the present application.Thus, the invention is comprised in three main portions or sectionsconsisting of a middle section A, a buck section B and a seatsees tionC. These three sections are adapted to be folded together to constitutea chair as seen particularly in Fig. l, and to be unfolded or opened inrespect to each other to form a couch or bed, as seen in Fig. 4, or inplan, Fig. 3. incident to vthis opening of the structure to constitute acouch or bed-it will be understood that the back B may bev moreor lessinclined than shown in Fig. 1 to form what is known as a recliningchair, and in this connection it should be understood also that theentire structure rest-s upon a base or floor trame F upon which themiddle section A ot the chair proper is engaged or released and owingtothe construction and relation of parts it was eX-w eeedmglyinconvenient to reach these hooks as wellv as its being veryobjectionable' toV always have this todo to make so slight aI change inthe structure. Hence we have de vised the presentmeans which areconvenient and etl'eetive and can be controlled from behind the chair bya small cord 2 when the spring laction ot the chair is to be restored'but which will be automatically locked by a spring 8 at, the 'front whenrigidity of the" parts is desired. v To these ends we employ front andrear swinging or pivoted brace rods suspended from the seatrame AA andwhich have their extremities bent down at right angles to form braces 4tandv 5 respec-` tively. The braces t at the front are shorter date theditlerences of distance between the two frames A and F at the front andrear respectively, but otherwise they are the same in construction andoperation. Links va conV nectsaid braces front and rear and have slots,6 intheir rear ends supported on pins on the braces and affording a`certainV amount ot' play between the said front and rear braces to accommodate their operations.

vIt will be noticed that the spring 5l is arranged in respect to braces4- m such way as to exert a closing action thereon with a 'constantspring tendency and through linkse also pull the braces 5 to closing orrigid position. The cord 2 is connected' with the braces 5 and adaptedto pull agalnst the spring to open position, and when the chair is to beconverted into a rocker the said cord is drawn far enough'to withdrawthe said braces and the extremity thereot is then engaged. on the hookor catch 7 on the back of the chair. Then as the chair is tobe maderigid again it is only necessary to release the cord and the spring 3will draw the.' parts' to Patent-fea Nov. 5, 1912. y

supportediby rocker springs S, the idea of than the braces 5 at therear, to accommo- Aioo` bracing position, and possibly a little rocklingby hand will help braces 5 to come to rocking chair by merely handlingthe cord ferred to is found' in 2, the end of which is alwaysconvenient, and the springs 3 and b close the braces.

Again, in the application above referred to We found that with astructure of this kind jointed here and tiere and depending upon theopening or spreading of the end sections to getthe desired tension tothe mattress M the mattress was liable to sag and did not afford ascomfortable a bed as it ought to., Hence we have improved the structureby introducing a series of spring Wires W transversely of the bedbetween the sides thereof and engaged with the top connecting bars 9 ofthe mattress supporting frame comprising the posts l0 with said bars orlinks, Vand which is adapted to fold as before. lVhen the bed is open orstretched the mattress M is sustained from edge to edge at its middle bythese cross wires, Which in a sense are incorporated-therewith andconstitute a portion of the spring mechanism for carrying the beddingwhich comes upon the Wire mattress. These transverse Wires W run at anangle to each other from side to side of the bed and are supplemented atthe front by a series of spirally wound sustaining springs G which restupon a cross piece g in the seat frame (1.1, The' said springs Gr and lVcooperate with each other and afford all the additional spring supportat the middle of the bed which is required in addition to the springaction Which the mattress M itself provides, and thus a very comfortablebed is made. he folded positiongof the several parts just describedcomprising the mattress M and the said -springs andthe frame 9 ,isclearly seen in Fig. 1,-where thesaid parts are `entirely removed fromobservation and occupy space which otherwise would not be occupied andWhere they are not in the way.

A 'third distinct and material improvement herein over the applicationabove ret-he means for making the back section B rigid with the middlesection A when the said back section is 'lowered more or less to ortoward its lowest attainable position as when used for a bed. In theforegoing-application a plain ratchet is shown as occupying the positionrelatively herein, but the said .ratchet -as said base section is liableto become detached in its engagements and particularly when the tensionof the mattress M is exerted te litt the back .B from the loweredposition seen in Fig. 4. rlhis frequently oet'furred, and hence in thepresent construction the ratchet 12 which engages on the cross portion13 in the frame has locking notches n at its pivot end adapted toabsolutely hold the head section-in the desired position when down toform a bed. For thatmatter all the notches of the .ratchet could be madein the same way with recessed ends, or their equivalent, and suchnotches are required when the back is lowered to an approximatelyhorizontal position wherein it ought to be fixed rigidly with theremainder of the structure and particularly since said back should holda given Iixed position on account of the mattress ilfhbeing connectedtherewith and dependent thereon to stretch the same to just therequisite tension. Otherwise the construction of the various partsherein and their operation is substantially the Same in the applicationabove mentioned and need not be more particularly referred to.' Thisapplies to the folding end frame la for the mattress and braces l5.

that we claim is:

l. A convertible chair and bed, in combination with a mattress thereinadapted to be strctclied lengthwise and to be folded upon itself whenout of use, and means to raise and support said mattress in usecomprising a head section to which the mattress is attached at one end,a loldable foot section and a .pivotcd sujiport for the other end ot'the mattress in saidhfoot section adapted to swing to an elevation clearof said section, a middle section on which said l'oot section is adaptedto be inverted and a pair of braces-engaging the middle ol said supportand pivotcd at the top and front oi said .middle-section.

2. A convertible chair? and bed having a base section and a back,section adapted to be lowered to approximately the same p lane adaptedto be inverted at the front of the base, in coml'iination with a springwire mattress attached at one cud to said back section and a 'loldablcframe pivotally n'iountcd on the bottom ot' said seat section having thefront. end ol. said mattress attached thereto, and braces for saidloldable frame engaged with said base section, whereby the mattressstretched when the bed is opened. j

3. A convertible chair and bed comprising head and toot and middlesections'respectively in hinged relations, in con'lbiuation with a wirespring mattress adapted to be stretched lengthwise to form a bed andengaged at its head end with the upper end of said head section, afoldable support for and a seat section 'Lonen-1 2 l l 1 support inraised position engaged at one end With said middle section and adaptedto i stretch the mattress automatically, and a double sidesupport 'forthe middle of the.

mattress oldably mounted on said middle section and having sideconnections at its top between its front' and rear portions and havingtlle'mattress attached to said .support 1o and )'oldable therewith. 1
